RADIATOR.

Specification of Letters Patent. Patented Apr. 20, 1920.

Applieatlon flled February 24, 1919. Serial No. 278,612.

To all whom. it may concern:

Be it known that I, Ennnvc 0. WEEKS,

citizen of the United States, residin at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Radiators, of which the following is a specification;

This invention relates to radiators for automobiles and the like, and the principal object of the invention is to provide 'means for receiving the overflow caused by the expansion of the water in the radiator and returning it to the radiator when the same needs refilling.

Another object of the invention is to pro vide means for automatically returning the collected water to the radiator when the water therein falls below a certain point.

Still another object of the invention is to provide means for producing a partial vacuum in the radiator by connecting the same to the suction part of the motor, such means being associated with means for breaking the connection when the radiator is full.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a sectional view of the front part of an automobile supplied with my invention.

Fig. 2 is an enlarged detail view.

Fig. 3 is a modification.

In these views, 1 indicates the radiator, which is constructed as usual and which is connected with the motor 2 in the ordinary manner. In carrying out my invention, I provide a cooling tank 3, which may be located at any suitable point, though I prefer to connect it with the lower part of the radiator, as shown in the drawings. This tank 3 receives the lower end of the usual overflow pipe 4, the upper end of which we tends into the filling spout 5 of the radiator. The tank 3 may be provided with a filling spout 6. Both of these spouts must be proiioat chamber is vided with caps and that for spout 5 must make an airtight fit, so as to revent any entrance of air to the radiator. lhe cap for spout 6 is provided with an air hole. In the upper part of the radiator is located a float chamber 7, the walls of which are perforated to permit the free entrance of Water thereto. The upper end of this chamber is provided with a port 8, which communicates with a pipe 9, which is connected with the inlet manifold of the motor. This port is controlled by a valve 10, located in. the float chamber and said valve is connected with the float 11 by the rod 12. It will thus be seen that when the water in the radiator is high enough to raise the float, the valve will cover the port and thus prevent the air from being exhausted from the top of the radiator by the suction action of the engine. A

check valve 13 is located in the pipe 9, so as to prevent any vacuum existing 1n the radiator from being broken by the flow of air from the engine to the radiator when tinengine is not running.

lVhen the system is filled with water and the engine started, the water will expand on being heated, so that it will rise above the overflow pipe and the water passing through this pipe will pass into the tank 3. When the water level drops in the radiator for any reason low enough to permit the valve to uncover the port 8, a vacuum will he created in the u per part of the radiator by the suction of tiie en ine, so that the water in the tank 3 will be (fawn through the pi pc 4 back into the radiator and this will con tinue until the water reaches the float 11 and raises the same to cause the valve 10 to cover the port 8, and thus prevent further ex hausting of the air from the radiator.

When the engine remains idle for anv length of time and the water becomes cool a vacuum will be created in the upper art of the radiator due to the contraction o the water, so that the water will be drawn from the tank 3 into the radiator to fill the same.

In this way, the radiator is automatically keptfilled, and when an anti-freezing solution is used in the radiator there is no dangel of the same bein discharged through the overflow pipe an lost.

In the modification shown in Fig. 3 the provided with a port in", which opens into the pipe'9, which is connected with the intake manifold as before vscribed, but the valve 10 is adapted to wntml a port 14 communicating with the upper part of the pipe 9' and opening out into :1 urge pipe 15, which leads to the tmusphere. In this w y when the flout s mined by the water in thd radiator the all will pass from the pipe 15 into tho pipe 9 wi l thus break the suctionjn the 1104!! cham- (.-I.' and radiator; as the port H is much hn'ger than the port 8" What I claim is:-
